Removal of Arsenic Ions from Aqueous Solution with Different Activated Stems

Abstract

Environmental pollution is one of the most serious problems we are facing today. The indispensability, deficiency or toxicity of arsenic is manifestation of dosage response effects blood is also a good indicator for presence of arsenic in human body. The objective of this study was to study the arsenic adsorption behaviour on activated stem ash of Salvadora Persica and Azadrichta Indica Batch studies were conducted using these adsorbents with aqueous solution different concentrations (0-500 μg/L) of arsenic. The adsorption capacity of the Salvadora Persica and Azadrichta Indica used in this study for arsenic was estimated as 92% and 86% respectively. The experimental data fitted well with the well-known isotherms namely Freunlich and Langmuir indicating a favourable adsorption by these adsorbents.
